Application filed October 23, 1912. Serial No. 727,438.

To all whom it may concern:

Be it known that I, ALBERT BERAN, subject of the Emperor of Austria-Hungary, residing at Hirschwang, Austria-Hungary", have invented certain new and useful Improvements in Roller Mechanism for Producing Corrugated Paper, Metal, and the like, of which the following is a specification.

This invention relates to improvements in roller-mechanisms for producing corrugated fabrics with either continuous or interrupted corrugations, in which pairs of corrugated rollers are used. Hitherto for producing different patterns of corrugation special rollers have for the most part been employed, in which the particular pattern to be produced at the time, is worked upon the top roller and the corresponding bottom roller.. Accordingly it has been necessary hitherto to mount in the rolling machine special pairs of rollers to suit the required pattern. Moreover the working of the pattern upon rollers was a costly operation. Gofi'ering or corrugating machines wherein one or both of the rollers are made up of a plurality sections of corrugating elements spaced from one another and displaceable longitudinally only on the roller shaft, permit only of varying the distance between the columns or strips of corrugated or goffered surface and plain surface, but permit of no variation of the actual lines of corru- *gation or gofi'ering, for instance from straight to wavy or zigzag. These objec tions are overcome according to the present invention by buildingu the top and bottom rollers of the machlnelof a number of disks lying side by side and adjustable circumferentially relatively to each other, 71c. capable of being rotated about their centers and set in any desired relative position.

Upon the circumferences of these disks are grooves, the composite profile of which produce the corrugations of the desired pattern. This construction of rollers presents the advantage that it is possible to produce with the same set of disks the greatest variety of patterns with continuous or interrupted corrugations.

One form of construction'of the rollers according to the present invention is illustrated in the accompanying drawing, as also the process for building up the rollers.

in Figures 1 to 6 are shown diagrammaticall-y diderent erns of corrugation produced with one and the same pair of rollers. Figs. 7, 8 and 9 illustrate in perspective three known patterns of continuous and interrupted corrugations made with the same pair of rollers. In Fi 10 is illustrated the top roller of a pair constructed according to the present invention; the cooperating bottom roller is formed in the same manner. Fig. 11 shows the top or bottom roller for producing a pattern as illustrated in Fig.- 8. Fig. 12 shows the c0nstruction of a top or bottom' roller for producing the pattern shown in Fig. 9 and the remaining figures show details of the construction of the rollers.

The rollers are made as follows :The

pattern to be followed is not divided. up according to the figural lines Z Z of the pattern, but each hne of corrugations is divided up into differential elements e by sections running across the, lines of corrugations. These differential elements 6 of the pattern are then transferred to the circum ferences of the thin disks 8 to form male and female dies and the disks assembled form the new roller. Owing to the formation of the rollers of a number of difierem .tial disks with differential corru'gating ele- A ments it is made possible to produce the greatest variety of patterns with a certain number of disks, since by moving the disks 8 about their centers relatively to one another the male and female surfaces of the roller can be altered at will. The great variety of patterns which may be obtained with a number of disks is illustrated in Figs. 1 to6. The pattern shown in Fig. l

groups of the differential disks 3 the same disks may he used for producing the pattern shown in Fig. 2 with a staggered row of corrugations. The patterns shown in Figs. 3 to 6 can he obtained in the s nc way by suitably disposing the disks 'Witl; regard to one another.

The roll r illustrated in Fig. 18 consists one another and upon the shaft. These are illustrated, for example in Figs. 13 to 14 and consist of a key-piece 4 let into the shaft Z upon which are engaged the disks 8 to s the disks being provided with grooves, which grooves may occupy different positions in the several disks. The teeth or grooves upon the circumference of the disks, as also the grooves for the key are stamped out of thin sheet metal. If necessary the disks may be held together by suitable keys v and grooves upon the sides of adjoining disks. 7

Having thus described my invention and explained the mode of operation thereof, 1 claim and desire to secure by Letters Patent:

1. An adjustable corrugating device including a hollow axle member rotatably mounted in suitable journals, and a cylindrical corrugating member including a plurality of thin duplicate corrugating disks mounted on said axle and each having peripheral projections, each of said disks being relatively adjustable with respect to all of the disks on the axle member to form corrugating projections of selected design,

and means for clamping said disks in position on the axle member.

2. An adjustable corrugating roll includ ing a plurality of duplicate thin metallic disks arranged side by side and flushly contacting from axis to periphery, said disks being capable of rotary adjustment independently or in groups, a plurality of spaced apart peripheral projections formed on each disk providing therebetween intervening corrugating spaces, said disks being adapted to be shifted into any selected longitudi nal arrangement of alinement to produce projecting corrugating elements on the face of said roller and corresponding interven ing corrugating cavities, and means for clamping the disks together.

3. An adjustable corrugating roller including a plurality of thin duplicate disk elements, said disk elements being arranged side by side and adjustable independently or in groups about their centers, said disk elements being also provided at'their peripheries with projections and intervening spaces to produce varied corrugating designs on the surface of said roller, and means for clamping said disk elements tightly together side by side in their adjusted relation.

In testimony whereof I affix my signature in presence of two Witnesses.
